Promissory Notes

What protections can a builder have against a homeowner selling their house?
A contractor agrees to provide self funding for a project that will cost the homeowner $20,000 with a $7,000 deposit. The builder will finance, out of his pocket, the remaining $13,000 over a period of 6 years. What protection can the builder have that the homeowner will not sell the house and skip town without paying the balance due? A lien in Pennsylvania must be executed upon within two years. If the homeowner is making the payments agreed upon, then the builder has no reason to execute on the lien. That doesn't appear to be the answer. If there were a confession of judgment in the construction agreement would that protect the builder? Please help. We have a service we will be selling to builders that may also need a law firm to represent them.
